Smarter than to take everything in the most crassly literal way possible? I would hope so.
I don't much like the story, and I don't believe in reincarnation, but to suggest that serious philosophy cannot be contained in a story that involves reincarnation is a pretty shallow view. At any rate, the whole "learn to become a god" thing that's the ultimate crux of the story is much more closely affiliated with Mormonism than Buddhism or Hinduism as far as I know.
